When i push the clutch pedal the noise dissapears but in gear (2nd or 3rd) during accelerate it comes back. I googled it and it sais the problem is with this driving shaft bearing.
Does anyone have experience with this problem. I am interested in how much does it cost or can i change it myself? I mean does it require special tools, etc.... I do everything myself on my car, i would give it a shot :D

 

Sounds more like possible input shaft bearing.

 

That is possible :D I am from Hungary and i have never even heard about this expressions in english so i googled it as well :D

 

Input shaft bearing requires removal of the transmission, unfortunately. Once the transmission is out, you will need a blind bearing puller to get it out. I used a slide hammer with a blind bearing attachment.

The intermediate shaft bearing requires some circlip pliers and a shop press. You could rotate the intermediate shaft and feel for roughness, and check for play.
